Hi, this is the first fm synth built in italy.. the sound seems to be really different than a dx7..is more analogue..it is based on same chip used by ek22 with all rest very different.. anyway is cheaper and warmer..and really hard for programming..if you find one you will be not dissapointed for the electric piano sound sounds..and some weird sounds..it is an hybrid of digital pre era technology and old analogue stuff..very cool..
